arc-furnace; DC; electric arc furnace; EAF (【技】利用电弧热效应熔炼金属和其他物料的电炉。按加热方式分为三种类型：①间接加热电弧炉，电弧在两电极之间产生。②直接加热电弧炉，电弧在电极与物料之间产生，是炼钢最常用的电弧炉类型。③埋弧电炉，亦称还原电炉或矿热电炉。电弧炉在各类电炉中的产量最高，使用最广，有时简称电炉。: ①Because post combustion technology is used, the EAF oxygen consumption increases from 26 Nm³/tonne to 42 Nm³/tonne, and the corresponding power consumption is 315kWh/tonne with a tap-to-tap time of 48minutes. 由于采用了二次燃烧技术，该电弧炉用氧量由 26 Nm³/t 提高到 42 Nm³/t, 相应的用电量为315 kWh/t, 出钢到出钢时间为48 min。②The EAF components fall into the functional groups: furnace structures for containment of the scrap and molten steel, components which allow for movement of the furnace and its main structural pieces, components that support supply of electrical power to the EAF, and auxiliary process equipment which may reside on the furnace or around its periphery. 电弧炉组件分成几个功能组：容纳废钢和钢水的炉体结构、用于炉体和主要结构件运动的组件、电弧炉供电组件以及炉体上或周边的辅助设备等。); electric arc furnace (① Much of the productivity gain achieved by the electric arc furnace over the past 10 ~ 15 years was related to oxygen use in it. 在过去 10 ~ 15 年中，电弧炉生产率的提高大多得益于炉内用氧。② The electric arc furnace productivity increased from 32 tonnes per hour to 85 tonnes per hour while power consumption decreased from 494 kWh/ tonne to 357 kWh/tonne. 该电弧炉生产率由 32t/h 提高到 85t/h, 而用电量由 494kW • h/t 下降到 357kW ・ h/t。) |
